The suspension has been fine. The 15" wheels may help a bit in this circumstance. We actually brought the rear up the other day to match the front better and allow for Cali roads.
Temps. look good as well, we upgraded to a set of SPAL fans. The only time you notice any difference is heat is after you run it then open the hood. A lot more heat greets your face
Brakes seem good too. The only difference I noted is in a little additional steering effort, though the alignment has not been done yet and that usually is the culprit.
